Zugg Software :: View topic - #EXEC on function sending an extra carriage return

Hello all,
I have a function that when called by a trigger, color the line of the mud, pretty simple.

For that, I'm doing this on the function:

#EXEC #COLOR "hi,green"

The line does get colored as I want, but the problem a blank line is sent to the mud as well, and I don't want that. How can I avoid it?

Thank you.

There is no reason to use #EXEC in that instance, i suspect that to be the issue.

The blank line might be caused by how you are calling the function. An alias would likely be a better solution for what you are doing, but that does not make using a function wrong. If you have the function call by itself on a line then CMud will send the results of the function to the mud, in this case a null result. The right way to use a function without sending anything anywhere is with the #CALL command.

Thank you Vijilante, using the same logic on an alias worked like a charm for what I wanted

Shalimar, the effect without #EXEC was the same, probably by the cause Vijilante posted after. Thank you too.
